godot 3d movement script code example

Example 1: godot platformer movement

extends KinematicBody2D # The player is a kinematic body, hence extends Kine..

# Adjustable variables of the player
# export is used to allow to edit the values outside the script
export var speed = 500 # The speed of the character
export var gravity = 32 # The gravity of the character
export var jumpforce = 800 # The jump force of the character

var motion = Vector2.ZERO 

func _physics_process(delta): 
	
	# Player movement functions:
	if Input.is_action_pressed("ui_right"): # If the player enters the right arrow
		motion.x = speed # then the x coordinates of the vector be positive
	elif Input.is_action_pressed("ui_left"): # If the player enters the left arrow
		motion.x = -speed # then the x coordinates of the vector be negative
	else: # If none of these are pressed
		motion.x = lerp(motion.x, 0, 0.25) # set the x to 0 by smoothly transitioning by 0.25
	
	if is_on_floor(): # If the ground checker is colliding with the ground
		if Input.is_action_pressed("ui_up"): # And the player hits the up arrow key
			JumpSound.play() # Play the jump sound
			motion.y = -jumpforce # then jump by jumpforce
	
	motion.y += gravity + delta # Always make the player fall down
	
	motion = move_and_slide(motion, Vector2.UP)
	# Move and slide is a function which allows the kinematic body to detect
	# collisions and move accordingly

Example 2: movement in godot

#3d
extends KinematicBody

var speed = 200
var motion = Vector2()

func _physics_process(delta):
	if Input. is_action_pressed("ui_right"):
		motion.x += speed
	elif Input. is_action_pressed("ui_left"):
		motion.x -= speed
	elif Input. is_action_pressed("ui_up"):
		motion.z -= speed
	elif Input. is_action_pressed("ui_down"):
		motion.z += speed
	else:
		motion.x = 0
		

	move_and_collide(motion)
